what does this thing look like?

f(t) = 10 u(t-1)u(5-t)u(t) ?

and what is the strategy to determine it? actually i need a laplace transform of it, but I need to simplify it first, then maybe i can do it by myself.

Thanks in advance.

t

t

t

simplifies to:

t in [1, 5]

So f(t) = 10 when t in [1, 5] and f(t) = 0 otherwise. Of course, if I've got this step function wrong, then you'll have to make appropriate adjustments, but there you go.

Now, since this is a pulse-type waveform, I can represent it as u(t-1) - u(t-5) and the appropriate laplace transform is simple.
